5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Antitussive Agents

Agents that suppress cough. They act centrally on the medullary cough center. EXPECTORANTS, also used in the treatment of cough, act locally. (See all compounds classified as Antitussive Agents.)


Narcotics

Agents that induce NARCOSIS. Narcotics include agents that cause somnolence or induced sleep (STUPOR); natural or synthetic derivatives of OPIUM or MORPHINE or any substance that has such effects. They are potent inducers of ANALGESIA and OPIOID-RELATED DISORDERS. (See all compounds classified as Narcotics.)


Analgesics, Opioid

Compounds with activity like OPIATE ALKALOIDS, acting at OPIOID RECEPTORS. Properties include induction of ANALGESIA or NARCOSIS. (See all compounds classified as Analgesics, Opioid.)
